I guess you might try calling IBM. They might be willing to tell you how to remove it, after all it IS your system and you shouldn't have to run anything you don't want to. But they may not have an actual removal capability, it might have been customized into Windows (though I doubt they could put anything in totally permanently since that would change the software and piss off Microsoft). If it can't be located in the Registry by that name, I can't imagine how it's placed there. You might try searching for an IBM or Thinkpad folder, and check the Windows and System/System32 folders for any files that might be related. The registry may be loading those file names instead of the specific item name.
